I have set up a honeypot in one of our segments. When someone logs into it, it logs the credentials into a log file. Using filebeat, I ship the new entries from the log to the elastic stack which looks like that on the dashboard.
Since I was given a 0 budget, is there a way to have the elastic stack send an email when that dashboard gets a new entry within the free tier? If not, is there a way to have the Linux OS send a notification when the log file gets a new entry with something like Postfix or Sendmail?
Huge thanks ahead.
